ARSA Technology Portfolio: Industrial RFID Terminal System for Busana Apparel Group

Project Overview

Client: PT Ungaran Sari Garments (Busana Apparel Group)
Location: Central Java, Indonesia
Sector: Garment Manufacturing – Industry 4.0 Digitalization
Solution Deployed: Custom Industrial RFID Terminal with Dual-Band WiFi + Ethernet
Production Volume: ~150 Units
Deployment Model: R&D → Mass Production → Factory-Wide Implementation
Application: Real-Time Production Progress Tracking at Worker Stations

Business Problem

Garment manufacturing operations face critical visibility and efficiency challenges:

• Production opacity: Management cannot track real-time progress of individual orders across 100+ sewing stations, creating delivery uncertainty and bottleneck identification delays
• Manual logging inefficiency: Paper-based or manual digital entry systems require workers to stop production, causing 15-30 seconds lost per item × 50-200 items/worker/day = 12.5-100 minutes daily productivity loss per worker
• Quality control gaps: No traceability linking defects to specific operators or production stages, preventing root cause analysis
• Inventory reconciliation errors: Physical counts vs. system records diverge by 3-8%, causing overproduction waste or shortage-driven delivery delays
• WIP (Work-in-Progress) management failure: Capital tied up in semi-finished goods without visibility into completion status or location

Industry Context: Indonesian garment sector handles high-mix, low-volume orders (50-5,000 pieces per SKU) for international buyers (H&M, Zara, Uniqlo). Late delivery penalties: 2-5% of order value. Quality claim costs: 10-25% of defective batch value.

Client Impact (PT Ungaran Sari Garments):

• 150 sewing workstations across production floor
• 20-40 concurrent orders in production
• 8,000-15,000 garments/day throughput
• Manual tracking causing 12-18 hour lag in production status visibility

ARSA Solution Architecture

Hardware Design

Industrial RFID Reader Terminal

Form Factor:

• Compact desktop enclosure (120mm × 80mm × 40mm approximate)
• Ruggedized ABS/PC plastic housing rated for textile manufacturing environment
• Anti-static coating (critical for electronics in fabric handling areas)
• Integrated mounting options: desk clamp, wall bracket, adhesive base

Core Components:

1. RFID Reader Module
   • Frequency: HF 13.56MHz (ISO14443A/B or ISO15693 standard)
   • Read range: 3-8cm (optimal for worker manual scan without removing garment from workspace)
   • Read speed: <100ms per tag
   • Multi-tag collision avoidance protocol
2. Display Interface
   • LCD screen (2.4″-3.5″ diagonal, estimated from images)
   • Blue backlight for low-light factory visibility
   • Real-time feedback: tag ID, worker ID, operation status, error messages
3. Input Interface
   • 16-key numeric keypad (0-9, A-D, *, #)
   • Purpose: Worker ID entry, operation code input, quantity override, system navigation
4. Connectivity (Triple-Redundant Network)
   • Primary: Dual-band WiFi (2.4GHz + 2.4GHz)
     • Dual 2.4GHz: Extended range for large factory floor coverage (50-100m)
     • Auto-failover between bands based on signal strength/congestion
   • Backup: Ethernet RJ45 (10/100Mbps)
     • Hardwired fallback for network reliability in RF-noisy industrial environment
   • Rationale: Triple-path redundancy ensures 99.9%+ uptime despite factory EMI (electromagnetic interference from sewing machines, motors, lighting)
5. Audio Feedback
   • Piezo buzzer (visible in top grille)
   • Success tone: Single beep (scan registered)
   • Error tone: Triple beep (invalid tag, duplicate scan, network failure)
   • Eliminates need for workers to look away from workpiece
6. Power Supply
   • 5V DC input (USB or barrel jack)
   • Power consumption: 2-4W typical, <8W peak

Operational Workflow

Daily Production Cycle

Pre-Shift Setup:

1. Supervisor activates terminals across 150 workstations
2. System syncs production schedule: Today’s orders, operation assignments, worker roster
3. Workers log in using employee ID via keypad

Real-Time Production:

Cutting Department → RFID Tag Applied to Garment Bundle
         ↓
Sewing Station 1 (Collar Attachment) → Worker Scans → System Records [Operator A, Station 12, Collar Done, 09:15:23]
         ↓
Sewing Station 2 (Sleeve Seams) → Worker Scans → System Records [Operator B, Station 18, Sleeves Done, 09:28:47]
         ↓
...continues through 8-15 operations per garment...
         ↓
Quality Control → Inspector Scans → System Records [Inspector C, Station QC-3, Pass/Fail, 10:42:11]
         ↓
Packing → Final Scan → System Records [Packer D, Station PK-1, Ready to Ship, 11:05:36]

Management Visibility:

• Real-time dashboard shows:
  • Order completion %: “Order #5423 – 847/1000 pieces (84.7%)”
  • Bottleneck alerts: “Station 22-24 (Buttonhole) – 230 pieces queued”
  • Worker productivity: “Operator 15 – 45 pieces/hour (target: 50)”
  • Quality flags: “3 defects detected in Order #5391 – All from Station 9”

Strategic Value Delivered

Quantified Operational Impact

Technical Differentiation

ARSA Custom Solution vs. Commercial Alternatives

Commercial RFID Readers (Zebra, Honeywell, Alien Technology):

• Price: $300-$800 per unit
• Designed for logistics/retail (not manufacturing line optimization)
• No integrated keypad for worker ID input
• Single-connectivity options (WiFi OR Ethernet, not both)
• Generic firmware requiring extensive customization

ARSA Advantages:

• Cost: 60-80% lower per-unit cost through custom design + mass production economies
• Integration: Purpose-built for garment worker workflow (keypad, immediate feedback, local buffering)
• Reliability: Triple-redundant networking (dual WiFi + Ethernet) eliminates single point of failure
• Customization: Firmware optimized for client’s exact operation codes, error handling, reporting requirements

Generic IoT Development Platforms (Arduino, Raspberry Pi-based):

• Fragmented: Separate purchases for RFID module, display, enclosure, network module
• No industrial hardening: Fails in textile dust, vibration, temperature variation
• Software complexity: Requires client to develop full application stack

ARSA Advantages:

• Turnkey: Single integrated device, plug-and-play deployment
• Ruggedization: Tested for 8-hour/day continuous operation in factory environment
